  摘要：Disasters mobilize hundreds of organizations, but coordination among them remains a challenge. This is why the United Nations has formed clusters to facilitate information and resource exchange among humanitarian organizations. Yet, coordination failures in prior disasters raise questions as to the effectiveness of the cluster approach in coordinating relief efforts. To better understand barriers to coordination, we developed a grounded theory and augmented the theory with an agent-based simul...
• Converting free users to paid subscribers in the SaaS context: The impact of marketing touchpoints, message content, and usage AI翻译

  摘要：As software-as-a-service (SaaS) becomes an increasingly popular business model, free-trial acquisition, which allows prospective consumers to explore the service at no charge, also becomes a norm for SaaS companies. However, empirical research on the role of marketing communications, consumers' free-trial usage, and their interactions is still lacking. This study utilizes the granular data from a leading SaaS firm that provides prospects with free trials and examines the impact of and interact...

  摘要：Motivated by the need of small and medium-sized hospitals to improve their platelet inventory management and achieve best practices, we consider an inventory system for a perishable product with a three-period shelf life over a finite horizon. In the system, the regular replenishment in each cycle is supplemented by an inventory adjustment opportunity in mid-cycle involving expedited orders and returns. We show that an optimal regular replenishment policy is an (s, S, S(x)) policy. Namely, if ...

  摘要：The requirement of social distancing during the COVID-19 pandemic has presented significant challenges for high-rise buildings, which heavily rely on elevators for vertical transportation. In particular, the need for social distancing has reduced elevator capacity typically by at least two-thirds or as much as over 90%$90\%$ of the normal amount. This reduction is a serious concern, as reduced elevator capacities cause large queues to build up in lobbies, which makes social distancing difficul...

  摘要：Overdiagnosis of breast cancer, defined as diagnosing a cancer that would otherwise not cause symptoms or death in a patient's lifetime, costs U.S. health care system over $1.2 billion annually. Overdiagnosis rates, estimated to be around 10%-40%, may be reduced if indolent breast findings can be identified and followed with noninvasive imaging rather than biopsy. However, there are no validated guidelines for radiologists to decide when to choose imaging options recognizing cancer grades and ...

  摘要：Reduction in hospital readmissions has long been identified as a target area for healthcare public policy reform by the US government. In October 2012, the Affordable Care Act (ACA) established the Hospital Readmissions Reduction Program (HRRP) program, which requires the Centers for Medicare and Medicaid Services to reduce payments to hospitals with excess readmissions. Even with recent changes in ACA, the HRRP program is still in place. In this study, we empirically examine the effectiveness...
• Integrated production and renewable energy generation in the presence of hydrogen energy storage AI翻译

  摘要：In this paper, we propose an inventory model that considers dual sources with energy storage to address the energy efficiency of an effective make-to-stock production facility that has access to grid electricity and a source of renewable energy, along with energy-storage capabilities. Such systems are being implemented in practice; however, the literature on inventory models does not offer solutions for extracting value from the management of such a complex energy mix coupled to energy-storage...
